A function stirling is available in PARI staring with SVN version r8396.

Could you be more specific ?

? ?stirling
stirling(n,k,{flag=1}): If flag=1 (default) return the Stirling number of the
first kind s(n,k), if flag=2, return the Stirling number of the second kind
S(n,k).

? stirling(5,2)
%1 = -50
